Abstract

A structure for storing digital data is provided, with a high reflectance layer comprising a gold film formed over a semiconductor layer, and a plurality of low reflectance portions comprising a mixture of a gold material and a semiconductor material. The plurality of low reflectance portions have top surfaces comprising more semiconductor material than the gold material. The invention also provides a method of changing reflectance on a data storage disk, comprising irradiating a laser light beam onto a gold film formed over a semiconductor layer, and raising the temperature of the gold film above a eutectic temperature for a mixture of gold and the semiconductor layer.
